Why should you inspect the air pressure in the auxiliary tanks?

Inspecting the air pressure in the auxiliary tanks is crucial because it directly impacts the proper functioning of various vehicle systems that depend on compressed air. Many systems, such as the braking system and certain suspension components, rely on adequate air pressure to operate effectively. If the pressure in these tanks is too low, it could lead to braking failures or impaired vehicle handling, putting both the driver and others on the road at risk. Thus, ensuring that the auxiliary tanks maintain the correct pressure is essential for the safe and efficient operation of the vehicle.

In contrast, checking the color of the tanks does not provide useful information about their functionality. While it’s important to ensure that tanks are not leaking, detecting leaks falls under a broader inspection of the entire system rather than pressure alone. Lastly, while air pressure might influence performance, confirming overall fuel efficiency is not directly related to the function of auxiliary air systems.
